Why do we need joints in our skeleton?

Answer 1

There are three main categories of joints. They are immovable, slightly movable, and freely movable. Immovable would be joints that are sutured together such as your cranial bones. Slightly movable involves the disc of cartilage between two bones such as your intervertebral discs. Freely moving includes many different ways of meeting up. This includes ball and socket (shoulder and hip), hinge (elbow and knee), pivot (first two vertebrae in spinal column), saddle (thumb), gliding (wrists), and condyloid (knuckles and jaw).

Answer 2

Joints allow for movement and flexibility in the skeleton, enabling us to bend, twist, and perform various physical activities. They also help absorb shock and distribute forces evenly throughout the body. Without joints, our skeleton would be rigid and immobile.

Answer 3

They allow for movement, basically. They also absorb the impact if a bone is hit, which is why joints are more likely to be injured than the bones themselves, like spraining your ankle.

Answer 4

there are different types of joints in the body because if there werent we wouldnt be able to move our bodyparts in different ways.

Answer 5

So we can move and bend. without joints our arms, legs ect would be straight.

Answer 6

We need joints to be able to move, walk, lift, and bend.

Answer 7
